Abstract

A finite element numerical model with progressive damage model was established to study the interface damage failure of composite hat reinforced panel structures with defects. Based on this, the effects of defect size and defect location on the tensile failure load of reinforced panel structures were studied. The results show that interface defects have an inducing effect on damage. When the defect size is small, the load-bearing performance of the reinforced wall panel changes little. When the defect size reaches 612.5mm², the load-bearing performance of the reinforced wall panel decreases by 11.94%. Different defect sizes can cause a reversal of the remaining load-bearing capacity during pull-off, that is, the larger the defect size, the smaller the pull-off failure load, and the greater the remaining load-bearing capacity; The distribution of interface defects with the same size on the x-axis is more sensitive than on the y-axis, and has a greater impact on the load-bearing performance of the reinforced wall panel. The research results provide a certain reference for the design and manufacturing of composite hat reinforced wall panels.
